2012 - Platinum Alloys

0.00

Most of the platinum that is produced around the world finds its use in industry as a catalyst and as a major constituent in various engineering alloys. Yet platinum has its distinct place in jewelry manufacturing. The subject of platinum alloys in jewelry has been discussed at Santa Fe Symposia in the past; however, the published information on metallurgy and properties of platinum alloys is quite limited. This presentation is an attempt to close such a gap. The objectives are to review the platinum alloy phase diagrams and the properties of platinum jewelry alloys, to explore some industrial alloys that also can be potentially used to manufacture jewelry, and also to present published data.
